Documentation of virulence and races of Xanthomonas citri pv. malvacearum in India and its correlation with genetic diversity revealed by repetitive elements (REP, ERIC, and BOX) and ISSR markers.

ABSTRACT: Thirty-four Xanthomonas citri pv. malvacearum (Xcm) isolates collected from three cotton-growing zones of India were subjected for virulence and race documentation and further correlated with genetic diversity as revealed by repetitive elements [repetitive extragenic palindromic (REP), enterobacterial repetitive intergenic consensus (ERIC) and BOX elements] and intersimple sequence repeat (ISSR)-PCR analyses. Among the 34 isolates tested for virulence on susceptible cultivar LRA 5166, 7 were recorded as highly virulent (HV), 16 were moderately virulent (MV) and 11 were less virulent (LV). Eight different races were recorded by using ten cotton host differentials. Twenty-two isolates (65%) belonged to race 18. Twelve isolates (35%) pertained to races 3, 5, 6, 7, 8, 11 a
